Graphene and Black Phosphorus Infrared Photodetectors

 · Invited

Abstract

In this talk, we will discuss latest development on infrared photodetectors based on graphene and black phosphorus. We will first cover graphene plasmon-enhanced mid-infrared photodetectors in which the detection leverages the bolometric effect in graphene nanoribbons. Then we will review the infrared detection properties of black phosphorus. Gated tunable black phosphorus photodetectors will also be presented, in which the bandgap of black phosphorus is tuned for the light detection up to the wavelength of around 8 μm. Finally we will compare the performance of infrared photodetectors based on graphene and black phosphorus and discuss their possible applications.
